La utopía interior: Superación del dualismo en los ensayos de Ernesto Sábato

My research attempts to demonstrate how Sábato’s essays have pursued a progressive path that reflects the evolving process of his vision. In light of his essays, I will delineate the themes of solitude, death, desperation, robotization of man, and finally, hope as the antithesis. In my analysis I examine the model created in Sartre’s Existentialism. I also visit the model followed by Nicholas Berdyaeff, who at least offers the possibility of salvation in a world conceived by and for Nothingness. I investigate how these and other tendencies had an initial influence on the essays studied in my research. I concentrate on those essays whose discourse is conditioned by the philosophical foundations of a being that inquires and discerns, discovers and denounces, and finally struggles with the impossibility of reaching the absolute. This foresight, at times apocalyptic, at times utopian, is already present in Sábato’s early works. In my study I attempt to establish how Sábato, in oscillating between the demonic and the romantic, the infernal and utopian, constructs his vision of the world through the symbiotic intertwining of both the fictional and essayistic genres. I focus on an author compromised by a constant debate with the paradoxes and dichotomies that, according to Sábato himself, define Modernity.

Biological Activity of Seed Proteins in Malesian Legumes

In a study of the effects on animals of seed protein extracts of 15 Malesian members of the Leguminosae (including 11 rain forest tree species), most of the taxa agglutinated red blood cells, induced mitosis, and inhibited amylases. These results are consistent with the hypothesis that these proteins interact with other organisms, most probably in defense mechanisms against predation by animals. The functions of these proteins are most profitably studied in rain forest environments where their activity is so marked, and where biological interactions are particularly important.

Frugivory and Seed Dispersal by Crocodilians: An Overlooked Form of Saurochory?

Saurochory (seed dispersal by reptiles) among crocodilians has largely been ignored, probably because these reptiles are generally assumed to be obligate carnivores incapable of digesting vegetable proteins and polysaccharides. Herein we review the literature on crocodilian diet, foraging ecology, digestive physiology and movement patterns, and provide additional empirical data from recent dietary studies of Alligator mississippiensis. We found evidence of frugivory in 13 of 18 (72.2%) species for which dietary information was available, indicating this behavior is widespread among the Crocodylia. Thirty-four families and 46 genera of plants were consumed by crocodilians. Fruit types consumed by crocodilians varied widely; over half (52.1%) were fleshy fruits. Some fruits are consumed as gastroliths or ingested incidental to prey capture; however, there is little doubt that on occasion, fruit is deliberately consumed, often in large quantities. Sensory cues involved in crocodilian frugivory are poorly understood, although airborne and waterborne cues as well as surface disturbances seem important. Crocodilians likely accrue nutritional benefits from frugivory and there are no a priori reasons to assume otherwise. Ingested seeds are regurgitated, retained in the stomach for indefinite and often lengthy periods, or passed through the digestive tract and excreted in feces. Chemical and mechanical scarification of seeds probably occurs in the stomach, but what effects these processes have on seed viability remain unknown. Because crocodilians have large territories and undertake lengthy movements, seeds are likely transported well beyond the parent plant before being voided. Little is known about the ultimate fate of seeds ingested by crocodilians; however, deposition sites could prove suitable for seed germination. Although there is no evidence for a crocodilian-specific dispersal syndrome similar to that described for other reptiles, our review strongly suggests that crocodilians function as effective agents of seed dispersal. Crocodilian saurochory offers a fertile ground for future research.

Examining the use of Simarouba glauca Seed Oil as a Feedstock for the Production of Biodiesel using a Small Scale Model Developed in India

Simarouba glauca, a non-edible oilseed crop native to South Florida, is gaining popularity as a feedstock for the production of biodiesel. The University of Agriculture Sciences in Bangalore, India has developed a biodiesel production model based on the principles of decentralization, small scales, and multiple fuel sources. Success of such a program depends on conversion efficiencies at multiple stages. The conversion efficiency of the field-level, decentralized production model was compared with the in-laboratory conversion efficiency benchmark. The study indicated that the field-level model conversion efficiency was less than that of the lab-scale set up. The fuel qualities and characteristics of the Simarouba glauca biodiesel were tested and found to be the standards required for fuel designation. However, this research suggests that for Simarouba glauca to be widely accepted as a biodiesel feedstock further investigation is still required.
